DTSF450 and DSSF450 series three-phase fourwire, three-phase three-wire electronic multi-tariffwatt-hour meter can be used for measuring active energy at three-phase four-wire system and threephase three-wire system. It adopts the latest MPU technology and digital energymeasurement chip of high accuracy and wide range, it has many features such as high accuracy, wide range, high stability, low power consumption and graceful appearance. Because LCD or LED and military components are used, it is characterized with long service life, free maintenance and convenient meter reading. It can measure positively and negatively, and has ability of anti electricity theft and pulse output, to take convenience for detecting. It is the first selection product for implementing national time-sharing electricity price policy.
